Visit to European Spallation Source (ESS) in Lund, Sweden

Together with the association for Danish Science Journalists (Danske videnskabsjournalister), I went to visit the European Spallation Source (ESS) in Lund in Sweden on May 10th, 2022. It was super-interesting!

ESS is a huge research facility under construction. When finished in a couple of years from now, it will be the world’s largest and most powerful neutron source. The principle behind it is that an extremely powerful proton-beam is shot into a large target (made of Tungsten), whereby neutrons are released and spread with large energy in many directions. These neutrons are guided through channels, and shot into different samples. By shooting neutrons onto the samples, lots of information about the sample is generated. The samples analyzed can be various different materials, biological specimens, archaeological specimens and more.

ESS is a collaboration between 13 different, European countries (of which Sweden and Denmark are the host countries) and is expected to give new insigths in various different research fields.
